According to process control experts, a detailed and specific set of control valve requirements is more than necessary when it comes to good control loop performance. Control valve selection plays a ...

By Jim Ford, PhD. Just over a decade ago, an article titled, "Advanced Control Strategies Move into the Field" (Control, October 2008), highlighted three evolving trends in the process control world ...

He provides control loop optimization services and training to industrial companies worldwide and has more than 20 years of experience in process control, including seven years in power plants.

Mike: Nearly every analog instrument uses the 4-20 mA loop. Field transmitters, positioners, and variable frequency drives ...

APC paradigm now more affordable, agile, scalable, and reliable. By Allan Kern, PE. In this article, as in industry, advanced process control (APC) refers primarily to multi-variable ...

Some wonder if AI will replace PID control loops. The reality is that, instead of replacing PID, AI is stepping in to help keep things running smoothly without upending regulatory trust. Think of AI ...

Two process control signaling schemes were to be supported — the 0 to 10 VDC analog signal, and the venerable 4-20 mA current loop. All that’s needed for both outputs is an Arduino and an ...

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but ...

Automatically collect process data for analysis. Assess the dynamic performance of control loops. Diagnose loop performance problems. Represent loop performance with a set of metrics.

Practical process control techniques including tuning single proportional integral derivative controllers, choosing appropriate control loops for a processing plant and measurement instrumentation. An ...
